IMPROVEMENT IN HARROWS.

The Schedule referred to in these Letters Patent and making part of thesame.

KANE, of Newport, in the county of Herkimer, and State of New York, haveinvented certain new and useful Improvements in Harrows .and we dohereby declare the following to be a full, clear, and exact descriptionof the construction and operation of the same, reference-being had tothe aocompanyingdrawings, making a part of this specification, inwhich-Figure 1 represents a iop plan of the harrow, as it appears whenarranged for work in the field;

Figure 2 represents a top plan of the harrow, as it 1appears when foldedup and arranged for transporta- Figure 3 represents a side-elevation ofthe harrow, as (it appears when spread out and ready for work; an

Figure 4 represents a side elevation, in section, of the hem-ow, asitappears when folded up and ready for transportation.

Similar letters of reference, where they occur in the severalseparate'figures, denote like parts of the harrow in all of thedrawings.

We are aware that fold-up barrows are quite common, and that runnershave been used in connection with barrows, on which they have beentransported. Of course, we lay no claim to such' things, irrespective ofour plan of constructing, arranging, and combining the several parts oithe barrow, to eifect the purposes hereinafter more fully set forth.

Our invention consists, first, in a harrow with runners, so hinged to itthat whenit is tolbe conveyed to and from the place where it is to beused, the runners can be lowered to the ground, and, at the same time,and by the same operation, the barrow is raised, and

when the hairow is to be used, said runners can be raised, and, at thesame time, and by the same mechanism and operation, the harrow can belowered to the'gronnd.

Our invention further consists in the use of runners, having hinges inthem, in combination with guides that deflect the front or curved partsof the runners away from the front of the harrow as the runnersaresaised.

Our invention-further consists in combining, with the hinged runners,and the. teeth or barrow-frame, the crank-rods, and lever, for swingingor moving one upon the other, as the case may be.

Our invention further consists in combining, with the leverandcrank-rods or axles, the catch for holdof the drag-bar, circular rail,and mechanism for ad jnsting the same.-

To enable others skilled in the art to make and use our invention, wewill proceed to describe the same, with reference to the draviiings.

The"liarrow-frame is represented as composed of three sections, viz, amain central section A, and two side or wing-sections B B, the latterbeing hinged to the formerat the points a b, respectively, so that theymay turn or fold up, on said pivots or hinges, toward the centralframe,and when so folded, they are held up by a link or hook, c, fastened toone and catching into the other.

When these two sections are letdown and used for harrowing the soil,they are capable of yielding to the surface of the ground over whichthey pass, and thus conform to itsinequalities,

On the central frame A are two crank-rods or axles d e, so connectedtherewith as that they may turn or be turned in their supports orbearings, by the operator seizing and manipulatinga hand-lever, f,connected to one of said crank rods or axles The crank-rods or axles d eare at their lower ends connected, by hinged or yielding connectionsatii, 85c, to the runners C, and these runners have joints or hinges inthem, at am, so that they may hinge or yield at said joints when raisedup to be carried on the harrow frame, or when let down to make themcarry the frame, the bent portions of said runners moving throughslotted guides n n, or their equivalents, on the harrow-frame, whichturn them backward from the front of the harrow.

At or near the front of the main barrow-frame is arranged a hingedcircular rail, 0, which can beraised or lowered at its extreme front,for regulating the depth that the barrow-teeth may enter the ground,said adjustment being dependent on the draught of the team, to anextent; and at 0' there is hinged a drag-bar, s, which lies or moves ontop of the rail 0,

and held thereto by an arm, t, upon it, which takes under said rail, sothat while the drag-bar may sweep around upon the rail, it cannot leaveit or rise from it.

On the lever f there is a hook, to, which, when the runners C are raisedup and carried on the harrowframe, takes under a catch, 1;, and so holdsthe lever and runners,

When the runners are thrown down, as in fig. 4, and theharrow-frame issupported by and carried on them, there is no necessity of' having anycatch or fastening, as the tendency of the load or draught of the teamis to keep the runners in the position in which they, are shown in saidfig. 4

It will be perceived that one operation of the lever f, as the case maybe, lowers the runners and raises the barrow-flame, or lowers theharrow-frame and raises the runners, so that one shall ride on orbecarried by the other.

We do not limit this application .of movable and hinged runners tojointed or fold-up barrows only, for

the hinged section may be taken off from our barrow,

without disturbing the runners or their action with the mainharrow-frame, though we prefer the hinged or fold-up frames, as they areconvenient and useful.

Having thus fully described our invention,

What we claim therein as new, and desire to secure by Letterslatent, is-

i. In combination with a harrow-fiame, the runncrs, so hinged to it tlnt when it is to be conveyed to or from the place where it is to'be used,said runners can be lowered to the ground, and, at the same time, and bythe same mechanism and operation, the harrow is raised; and when theharrowis to be used, said runners can he raised and the harrow lowered,by the same mechanism and operation, substantially as herein describedand represented.

2. Also, in combination with the barrow-frame and the runncrs, thehinges in the runners, and the guides on the frame, so that the front orcurved parts of the runners shall be turned backward from the front ofthe harrow when they are raised, substantially as described.

3. Also, in combination with the frame and runners, the crank-rods oraxles, and the lever, for raising or lowering one upon the other,substantially as described.

4. Also, incombinationwith the lever and crankrods, for raising orlowering one part upon the other, the hook and catch, or theirequivalents, for .holding the runners up upon the frame, substantiallyas described.

5, Also, the combination of drag-bar and rail with the mechanism bywhich they are made adjustable, substantially as described.
